VAPOR-BURN ER STOVE.

SPECIFICATION forming part of Letters Patent No. 416,040, dated November26, 1889.

Application filed June 2l. 1889. Serial No. 315,112. (No model.) v l Toall whom it may concern:

Be it knpwn that I, HENRY RUPPEL, of Cleveland, .in the county ofCuyahoga and State of Ohio; l1ave invented certain new and usefulImprovements in Vaponurner Stoves; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse it, reference being had to the accompanying drawings, whichform partof this specification.

, My invention relates to an improvement in vapor-burner stoves; and theobject-s of myv invention are to dispense with the usual lighting-cupand' substitute therefor a reservoir which is lled with packing, andthrough which air and gasoline are forced for the purpose of producingvapor, by means of which the central burner can beinstantlylighted; toplace upon the stand-pipe a gen erating-chainber which is divided by apartition into two separate and distinct chambers, and which hasaperforated top, the inner chamber being fed with vapor by the centralgeneratingburner and the outer one by the two end burners, the Hainefrom the generating-chainbers being used both to generate vapor for thecentral burner and to relight the end burners should they becomeaccidentally extinguished at any time, and to do away with the ordinaryneedle-valves, which are oper-y ated by hand wheels or levers, and tosubstitute therefor endwise-moving grooved needle-valves, which areoperated by pinions, and which can be changed when they become worn atany one point.

Figure l is a front elevation of a vaporburner stove embodying myinvention, the name-plate and the levers connected to theoperating-stems being removed in order to show the parts more clearly.Fig. 2 is a side elevation of the same, the end burner being removed.Fig. 3 is a plan view, 4a portion of the central burner being removed.Figs. Il

and 5 are detail views of the slotted nameplate and the levers foroperating the valves which control the flow of vapor to'the end burners.ator.

A represents the pipe which conducts gasoline from the tank to thecentral burner, and

Fig. 6 is a plan view of the gener- B the stand-pipe, upon which thecentral j generating-burner C is placed. This vstandpipe is connected toa T-shaped pipe or casting D, which is connected to the pipe A atopposite ends or sides, has two connections extending at right anglesthereto for the reception of the hollow valve-stem and the reservoir,and another connection d, which eX- tends vertically, and to which thestand-pipe Bis screwed. Leading from the top of the stand-pipe is thevapor-pipe E, which is provided with a controlling-valve E forregulating the iiow of vapor to the central burner C, and from whichpipe extends at an angle the pipe G, which has its outer end c turned atan angle so as to be in line with the pipe H, which extends from thecentral burner C, and which end e contains the needle-valve, whichcontrols the flow of vapor into the pipe II. This needleaf'alve isregulated in the rst instance by means of a screw-plug I, and which isnot .afterward changed except when it is desired to clean the needle orthe pipe, or under similar circumstances. This needle is thus locked upout of the way, so as not to be injured by persons operating itunnecessarily. The plug-valve E is intended to control the flow of vapordirectly from the stand-pipe, and the needle-valve is not to be operatedafter it is once adjusted.

lleretofore lightingcups have generally been employed for starting `thestove in operation; but these are objectionable on account of the smokeand re and the blackening of the stove wherever the flame touches. In

the reservoir J is used, which is screwed Yupon the arm K, which extendsfrom the coupling D. This reservoir is filled with a packing of anysuitable porous material, and extending from the top of the reservoir isthe pipe L, which is provided with a stopcock to control the flow ofvapor or gasoline through it, and which pipe has its outer end 4reducedsomewhat and bent at such an angle as to discharge directly into thepipe H of the central burner C. Extending from the coupling D, in adirect'line with the pipe K, is a second internal screw-threaded pipe M,through which the hollow valve-stem passes. To the outer end of thisvalve-stem Ico N is secured a bulb or other air-forcing mechanism Q, andconnected to the stem is the operating-lever O, by means of which thestem can be revolved. The inner end of this stem N forms a valve andlits into a seat made in the inner end of the pipe K for the purpose ofregulating` the .iiow ot' air and gasoline into the reservoir J. Whenthe stem N is given a quarter-turn, so as to move its inner end from offits seat in the end of the pipe K, and the bulb Q or other forcingmechanism is operated, air and vapor are forced into the reservoir J,and from this reservoir, when the stopcock in the pipe L is opened, thevapor passes into the central generator, and from which burner the vaporis lighted. .Afew operations of the bulb oi other ainforcing mechanismwill force a sufficient supply of air into the reservoir to supply vaporenough to start the central generator, and then the stem N should begiven a quarter-turn by means of the lever O, so as to close the supplyof gasoline to the reservoir J. The stop-cock is placed in the pipe L,so that the flow of vapor from the reservoir can be shut off whenever sodesired.

By means of the construction above described vapor is always held underpressure in' the reservoir, or can be instantly generated, so that thecentral burner can be lighted like gas,l thus enabling the ordinarylight-ingcupl toy be entirely dispensed with.

Extending downward from the central burner C is a pipe R, which conductsa portion of the vapor from the mingling-chamber into the inner chamberS of the generatingchamber. This generating-chamber T is di-l vided by avertical partition U into the outer chamber V and the inner chamber S,and the two cham bers are provided with a perforated cover a, throughwhich the vapor escaping from one or both of the chambers burns.inner-chamber S is in contact with the upper end of the stand-pipe; butthe heat from this chamber is intended to vaporize the fuel inthestand-pipe B and to heat the two supplypipes W, through which vaporpasses to the end burners X. The'two chambers S V have no 'communicationwith each other, and while the chamber S is in use all the time that thecentralburner is being used the outer chamber V is only brought into usewhen one or both of the end burners X are being used.

The flow of the vapor from each of t-he pipes W is controlled by anendwise-moving needle-valve Y, which has a series of verticalgroovesmade in its stem,an d which valve is operated by the pinion Z,theteeth of which catch inthe grooves and move the needle back and forth asthe pinion is caused to partially revolve bythe stem A'. Each of thevalves Y isl grooved circumferentially in its stem, so that when any onepart becomes worn by the operation of the pinion Z the valve can -beturned partially around, and thus bringa new' surface into play. Thisconstruction also enables the valve to be removed and replaced,

The.

so as to present a new surface-at the pointin case the valve should nottit perfectly to its seat.

If the grooves or teeth upon the valve-stem were made upon one sideonly, the valve would always have to be used in just one position,because thepinion cannot operate it at any other point. The vaporescapesfrom the end of the pipe W into the conducting-pipes B' of the endburners X. Extending parallel with the conducting-pipes B' andconnecting with the outer chamber V of the generator T, at one end andthe bottom of the outer burners X, are the pipes C', through which aportion of the vapor from each end burner X passes backward to thegenerator, and, escaping from the top of the chamber V, is burned atthat point. Extending from, each' end burner X, "and having its inneropen Aend placed just above the top of the chamber V, is aconducting-pipe D', through which a-portion of the vapor escaping fromthe end burner or a portion of the vapor escaping from the chamber Vpasses. Should the end burner become accidentally extinguished, aport-ion of the escaping vapor will-be caught in the end of the pipe Dand pass backward toward the generator at the same time thata portion ofthe lighted vapor from the chamber V will enter its inner end. Theconsequence is that flame will follow the gas through th'epipe D andlight the extinguished burner; or should the flame arising from bothchambers of the generator become extinguished av portion of the escapingvapor will be caught by theinner end of the pipe D' and beV carried outtoward the end burner, at which -point'it will be ignited, and then theflame will be passed backward through the pipe D' for the purpose ofrelghting the generator. InI this manner, should any one or two of theburners become extinguished they will be' automatically relighted byhaving the amepass through the pipes D', as above described. Should thecentral burner become extinguished at any time and the generator remainlighted, the flame will pass up around the sides of the burner C andrelight.

By the constructionl above describedI lrave, by dividing the chamber Tinto two annular chambers, combined the ordinary iiame of the innerchamber S with the hotter iiame of the mingled vapor and air from theouter chamber. Incase the central burner alone is used the ordinaryiiame from the chamber S is sufficient-to generate the vapor andthe IOOIIO

formed in the name-plate. These slots are preferably made curved, and atone end of each slot there is made a notch or shoulder L' behind whicheach handle or lever I' drops for the purpose of locking the valve Y inposition when closed. These notches or shoulders are formed so that thehandle or lever cannot be accidentally moved in such a manner as to openthe valves Y and permit an escape of vapor by having the dress or someobject strike against them. The other end L" of each of the slots fromthe shoulders or recesses L' are suitably enlarged, so as to allow thelevers or handles to drop down therein, and thus hold the valves openal'ter the burners have been lighted.

Having thus described my invention, I claim- Y 1. The combination, witha vapor-burner, of an air-forcing device connected to the suppl y-pipewhich extends from the tank, a reservoir also connected to thesupply-pipe and into which air and gasoline are forced, and a pipe whichextends from the top of the reservoir and conducts the vapor to theburner, substantially as shown.
